Application tiled May El,

tina` oi the breastcurve in the front portions of tlaebeels.` rllhisoperation takes place immediately after the sawing ot the rough block,and before the turning of the lateral curved surface.

The grooviiig operation hasheretoiore been performed by placing theblank in a holder and traversing the holder b y hand Vover a. cutterarranged to torni the proper curve. lt has been proposed to perform the.operation automatically by feeding the holding1` instrumentalityoperating in con il nection With a carrier to support the blankspositively and effectively against the tool pressure. Advantageously theblank is auto- `matically gaged on the carrier 4in proper relationto-the tools betoreit is engaged by the jack, and still anotherimportant feature of the invention consists in the arrangement of theacking instrumentality to grasp lthe blank. The `forces applied to theblank during jacking and unjacking are thus varied slowly anddisturbance of the blank on the carrier is avoided.

The rolling' jacking and unjacking action `above described isadvantageous Jfrom an other point of view. There is, as will beseen,inore than one tool necessary to effect the proper groovingoperation, and it has been found that a device which holds the i blankjacked continuously While passing1 all the tools gives trouble inoperationz` ii it is to move with the blank, it must be mechanii, fr fra f MitEESAGEE'SIETTEE, A CORFORATNUF seriai no. sienes.

cally complicated. and if it does not move with the blank much frictionis generated. By the present inventiomthe blank is jacked only 'when inengagement with a tool, and as stated, the j tickingand unjackingaredone so gradually as not to disturb the tion or the blank on thecarrier. j

The invention also provides an improved gaged posi- `device forremovingl linished Work from the machine, a ieature of Which is anadjustment to follow gaging, movements ot the carrier in order topreserve the operative relation between them. j i

These and other teatures ot the invention comprising certaincombinations and ar rangements of parts will be understood from thefollowing description ot a preferred enibodiinent thereof selected torpurposes et illustration and sliovvn in the accompanying drawings inWhich,` 1

The main trame l0 ot the machinecarries detachable brackets l2 and l/lin which are mounted `iii anyconvenient manner electric motors 1G. 1'2"with vertical. spindles 18, 19

carrying` at their upper fende the finishing and roup'hingcuttersQO andQQ, respectively. "lhe spindles ot these motors, as

shown.` are in a vertical plane parallel to an endless belt carrier 24which is traversed pastthem in the direction oi? the arrow in Fig; lover the sprocket Wheels 26, 28, which are driven in anyappropriatemanner. A third sliait 30 having;` a Wabble-saw at its upper end isdriven by a direct connected motor Se, the Whole construction being'pive ol'ed at in the bottom ot the main trame to permit adjustment. Theupper endet' the sbatt has bearings in a plate 38 mounted to slide inguide d() on the trame l0 and adjustable therein by means oft a screwand bolts del. This adjustment moves the saw toward and from the endlessbelt carrier about the pivot 36 in orderto page aantonen 'ro stier-nnporri i arranged `to correspond approximately to `the centers of thecutting` strokes ol the "from accidental displacement on the endlessbelt carrier and they pass under the jack Wheel 104 Without disturbance.

i Theteeth ot these jack wheels are spaced suihciently close together sothat at least one ot them `will certainly strike a Work blockin anyposition upon the endless belt carrier and they are set so low in theslides that a substantial compression of the springs is effected so thatthe work blocks are held very firmly. f

It vvill be observed that the large diameters of the idler Wheels ascompared with the dimensions of the wood heel blocks `ejive them alongarc of contact with the blocks and enable them to hold the blocksirmly during` the entire time that the cutters are operate ing on them.i

After passing the second cutter which is arranged to remove perhapsone-eighth inch of stock, the 3vvork blocks pass out to the lett infFig.1 and are removed trom the carrier by anarm 124.` This arm is pivotedupon a horizontalpivot in a block 128 having a cylindrical portionl`mounted for vertical movement in a plate 182 and held by a set screw`134 which engages a peripheral notch in the `cylindrical portion 180.the notch beine-` ot considerably greater Width than the thickness ofthe screw so that the cylindrical portion 130 can move up and down inits holein the plate 182. A pin 136 is mounted upon the lett hand end ofthe plate 58, and supports the rear end ot the member 124. This pin isof such length that as the plate 58 is adjusted up and down, it

will raisethe rear end of the member 124 to a sutlicient height topermit the passage ot the partitions 54 under it, thisverticaladiustniient of the member 124 beingperj mitted by movement ot the stud130 in its hole. The finished Work blocks as they come oli' at the leftstrike the slantine1 edge 138 of the member 124 and are pushed oil thecarrier into a conveniently situated barrel.

The partitions 54 Will always be oi such height as to permit the upwardprojection oi any Work block beyond their tops. In case any Work blockpasses under the momber 124 'for any reason, the member 124 can tiltupwardly around the end` ot the pin 136 and the block Will be carriedaround toits outer end 140 and drop on the floor. This upward movementis steadied by the engagement ot a iin 142 mounted upon the member 124Witha corresponding-ly upwardly ei:-`

tending;` iin 144 on the member 132, a pin and slot guide at 146 beingprovided. A spring 148 extending between the block 128 and the member132 holds the member 124 `in its lon'ermost position in contact with theupper ends ot the partitions 54. lhe mein-- "ber 182 is pivotcd at 150to permit horizontal movement upon the table 152 upon,

which it rests. rihis movement is guided by a pin,` and. slotarrangement at 154 and the member 132 is held. in the position shown inFig. 2 by a spring 156. Thus in case a block becomes jannned against thetace 188 in some r' `way both plates 188 and 132 vvill swing toward thebottom olr Fig; 2v around the pivot 150, allowingr the block to becarried over the wheel 126 and dropped upon the floor. j

In operation, the attendant puts the blocks 68 into the pockets on thelinks as rapidly as they come up on the Wheel 28. `They are carriedagainst the arm i() and pressed` against the gage 50. They then passunder the hoiding' member 88 which scores, their tops and holds themagainst the `pressure ot the saw 32 Which trims ofi' the lip at thebreast. They then pass from under the member 88. under the jack Wheel102 which has been suitablyv adjusted in vertical and horizontaldirections and which holds them iirinly against the pressure of' theroughinig cutter v22. They then pass from under this Wheel and shoeacross tothe similarly ad jnsted Wheel 104 which holds them likewiseagainst the pressure of the finishing' cutter 20, after which they passto the knock-ott erm 124 and fall into the receptacle arranged toreceive the1n.`
